For one, I am trying to put pics and music from my computer onto my phone. theres a ton of info on how to get it from phone to computr, but not the other way around. I am trying vrizons vcast media manager right now. not working..?

second, every time i plug my phone into my computer it says there is no sd card. everytime i unplug it it recognizes it and whatnot. i dont understand why it does this...? i need it to recognize the card WHILE its plugged into the computer to switch any media onto it. UGH!
